Here are some floor plans and elevations to show the process of how we developed one final idea.
Kakadu is located in the tropics, 12 to 14° south of the Equator. The climate is monsoonal, characterised by two major seasons: the dry season and the wet season. The 'build up' describes the transition between these two seasons.
During the dry season (April/May to September), dry southerly and easterly trade winds predominate. Humidity is relatively low and rain is very unusual. At Jabiru the average maximum temperature for June-July is 32°C.
During the 'build up' (October to December) conditions can be extremely uncomfortable with high temperatures and high humidity. However 'build up' storms are impressive and lightning strikes are frequent. In fact the Top End of Australia records more lighting strikes per year than any other place on earth. At Jabiru the average maximum temperature for October is 37.5°C.
The wet season (January to March/April) is characterised by warm temperatures and, as one would expect, rain. Most of the rain is associated with monsoonal troughs formed over Southeast Asia, although occasionally tropical cyclones produce intense heavy rain over localised areas. At Jabiru the average maximum temperature for January is 33°C.
Annual rainfall in Kakadu National Park ranges from 1,565 mm in Jabiru to 1,300 mm in the Mary River region.
The following charts provide an indication of rainfall, temperatures and humidity within the Kakadu region. Data for the charts was sourced from the Bureau of Meteorology, Darwin.
Solar Panels
Almost two billion people in developing countries -- one third of the world's population -- have no access to electricity. Fuelwood, agricultural residues, human power and draught animals continue to be the primary energy resources for millions of rural families.
Finding alternative sources of energy that are both economical and environmentally friendly is crucial for increasing agricultural productivity and improving the quality of life in rural communities. A new FAO publication, "Solar photovoltaics for sustainable agriculture and rural development", suggests that photovoltaic solar energy systems may be part of the solution.
Finding the right niche
The publication makes clear that photovoltaic solar systems are still relatively costly and therefore are not "a panacea for solving all rural poverty problems". However, they do offer tremendous potential for filling certain extremely important 'niche applications'.
"Solar energy systems, together with wind energy and other renewable energy applications, are the only technically viable solution to deliver the energy required by isolated rural communities," says Gustavo Best, FAO Senior Energy Coordinatorin a radio interview. "Small amounts of energy can make a tremendous difference, making it possible to improve rural lives, enhance agricultural productivity and create new opportunities to earn income."
Solar power is currently used primarily for household lighting and radio and television. By extending the hours of available light, it creates extra time for productive activities. This has been especially beneficial to women and children, who spend more time indoors. The extra light allows women to perform activities such as sewing, basket-making and handicrafts and lets children continue studying after dark.But solar energy's potential is relatively untapped in increasing agricultural productivity and rural development in general. With a supportive financial and institutional environment, solar energy systems could significantly improve health care and education; water supply for consumption, irrigation and livestock; food preparation and refrigeration; veterinary services; communication; and tourism. It also holds promise for productive off-farm activities (restaurants, cinemas, technical and artisinal workshops, etc.) by powering tools, kitchen equipment, phones and other appliances.
